No complaints here. When they work they work.
When they don't work, parts are really cheap.
I can think of many brands that have something that always goes wrong, ie a known regular fault. And the parts for them cost more when that almost guaranteed fail happens.

If LG is all you are worrying about, you should see the list of cheap chinese knock off a/c units available down here.

At least you don't need to know option codes for LGs unlike another korean brand.

I don't recommend LG to anyone, but I deal with repairing them a fair bit (no more repairs needed than any other brand though) They have a 5 yr warranty down here like any main brand, so the ones I see have run for quite a while.
